In chemistry there is the law of the preservation of mass. Even the ashes, water and smoke of a burnt tree trunk together weigh as much as the trunk did before. Nothing is lost in the transition.
I think, there is also a law in the world of the preservation of value. Gold remains gold, love remains love, shit remains shit. You can relate this teaching to every area of life. If you eat badly, your body cannot perform well. If you go through the world without love, you will experience little love. If you work for bad people, you cannot do a great job.
Turning shit into gold is like transforming minced meat into a vegetarian dish through ravioli. Works well until someone bites into this shit. Shit never becomes gold, because shit always remains shit. What’s inside comes out.
